我想從配置文件中加載所有url。我創建了一個名爲JSON文件「config.json」,ConfigurationService.ts度日關鍵的網址,但我不能鍵獲取URL從Angular 2中的config.json獲取數據
config.json:。
{
"loginUrl": "http:example/login",
"verifyUrl": "http:example/verify"
}
ConfigurationService.ts :auth_service.ts的
import {Injectable} from '@angular/core';
import {Http, Response} from '@angular/http';
import {Headers, RequestOptions} from '@angular/http';
import {Observable} from 'rxjs/Observable';
@Injectable()
export class ConfigurationService {
constructor(private http:Http) {}
private result: Object;
getConfiguration(key) {
return this.http.get('./app/config/config.json').map(res => {
res.json();
this.result = res._body;
return this.result[key]; //returns 'undefined', but when I return only 'this.result' it shows me all json data {...}
});
}
}
部分:
private x =this.configurationService.getConfiguration("verifyUrl").subscribe((result) => console.log(result));
如何只接收例如loginUrl?
啊哈。我看到我的錯誤。謝謝:) – Serhiy
